Abstract
A packaging arrangement for the containment in a blister package of at least one hydrophilic contact lens in a sterile aqueous solution. Provision is made for incorporating support structure in the form of stiffening groove or wall elements in flanges of base members of the blister packages to facilitate an improved attachment between the base members of the blister packages housing the contact lenses, and a flexible cover sheet utilized for sealing engagement with the base members while incorporating additional strength to the blister package structures.
